I have just come across Mulch Net.com. This is advertised as connecting tree loppers and vegetation management people with people that want mulch.
I have registered in the hope that I will get some mulch for a revegetation project that I am hoping to commence on my property in the cooler months, but it seems that there aren't any loppers currently registered in my area.
Nevertheless, I think this is a fabulous resource and a great way to connect people and ensure that resources aren't going to go to waste (hee hee hee).
Maybe it might work for you in your area.
